One Piece: I, Ace, the Eclipse King!

Transmigrated as the bloodline of Pirate King Roger, Portgas D. Ace? Thinking about becoming Whitebeard's obedient son in the future, only to have Akainu punch through his chest? Screw that, forget the plot armor! In this life, his soul has mutated, granting him perfect dual Devil Fruit potential! Left hand holds the Yami Yami no Mi to devour all, right hand wields the Suzaku's divine flame to incinerate the abyss! Garp's iron fist? I've learned it! Roger's saber? I've taken it! Training with Sabo in hell, setting sail at seventeen, building the Eclipse Pirates, a crew of monsters! "Pirate King? That boring title for playing house, whoever wants it can have it." Ace draws the supreme grade sword at his waist, laughing arrogantly: "What I want to be is the one and only king of this sea."
